    pub items: Vec<Arc<Expression<T>>>,
}

Gets the average value.

Fields

Trait Implementations

impl<T> Clone for Average<T>where T: Evaluate + Kind + Clone, T::Output: From<Value> + Into<Value> + Clone,

fn clone(&self) -> Average<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Average<T>where T: Evaluate + Kind + Debug, T::Output: From<Value> + Into<Value> + Clone,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Evaluate + Kind> Evaluate for Average<T>where T::Output: From<Value> + Into<Value> + Clone + Zero + AddAssign<T::Output> + Div<f64, Output = T::Output>,

type Output = <T as Evaluate>::Output

fn evaluate(&self, args: &EvaluationArgs<'_>) -> Self::Output

Evaluates the thing.

impl<T> Kind for Average<T>where T: Evaluate + Kind, T::Output: From<Value> + Into<Value> + Clone,

fn collect(&self, exprs: &mut Vec<usize>)

fn is_trivial(&self) -> bool

Trivial expressions are ones that don’t require any calculations being made. Trivial expressions should not be cached, as it is much faster to evaluate them than to get their caches.

fn evaluate_weights(&self) -> Weights

Evaluates weights.

impl<T> Serialize for Average<T>where T: Evaluate + Kind + Serialize, T::Output: From<Value> + Into<Value> + Clone,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
